There's no minimum damage.

The ignores armor description should be clearer: only apply ignores armor if the magic really does not care about armor.

A spectral blade that passes through flesh and steel leaving it frozen (and painful) sure ignores armor.

Magic missiles are just projecticles of force, they get slowed down by armor like anything else.

Fire's still going to heat (and squeeze in) through armor, so fireball ignores armor.

It all depends on the fiction! We're going to be adding some margin notes to that example to cover stuff like this.

So those goblins are all charging together, right? It's one charge, so I let Ben spend one hold to redirect that one attack.

Attacks from multiple monsters together mean you reroll damage for each and take the highest result. d6 damage for goblins means 5 is a pretty great result.

Now all of this only applies when it really is all one attack. If those three goblins are coming from different directions? No way. If they're not helping each other? Nope. But when they really are attacking in concert it's one attack with damage rolled for each using the highest result.

If you're down with Django and python that's my preferred approach (I have hateful memories of PHP) but hey, I'm open to anything. I toyed around with it just a bit today and it seems very possible.

I'm totally unfamiliar with Glorantha except for playing Lord of Dragon Pass (or was the King of Dragon Pass? That one game that got re-released for iOS lately...). That said, here's some ideas:

If magic is that common it should probably be in the basic moves (since basic moves = things everyone can do). You could either make it a specialized Defy Danger or make a new move for it, possibly with the spells available being class dependent. Something like "When you cast magic bestowed by your training" or whatever.

Bonds are a great place to add cults. A bond should probably entitle you to some kind of bonus (maybe only usable one, like "mark off a bond to get aid from your cult as appropriate to your standing...") and an XP payoff ("...and mark XP").

Seems doable, yeah.

stras, any chance if you have a prototype you could throw it up on github? I'm low on time at the moment (I'm getting married in just under two weeks) but sometime I'll have time to contribute.

Stras, how do we style the headers in user inputed text in that process? (Or do we just not bother?) Like when the user adds a move called "I Like To Move It" how do we put "I Like To Move It" into the header font/style?

jj, I looked at doing something similar, but ultimately ended up not having the time to put into it. It does seem entirely possible, but my expertise isn't really in web apps. (For those who don't know my day job is software development, but I'm more in the client/app space than server-side.)
